Bug description:array_walk 3rd parameter not modifying by-reference
Description:
------------
third parameters of array_walk function is not changing unless I used the
deprecated syntax of call-by-reference
Deprecated message is shown and its working properly that way.
Test script:
---------------
$cont = 0;
$sampleArray = array(0,1,1,2,3,5,8,13);
$foo = function($item,$key,$aux){
$aux++;
};
array_walk($sampleArray,$foo,$cont);
echo $cont; // it's ok. cont = 0, no call-by-reference
echo "<hr>";
$cont = 0;
$foo = function($item,$key,&$aux){
$aux++;
};
array_walk($sampleArray,$foo,$cont);
echo $cont; // it should be same as count($sampleArray) but it is 0 BUG!
echo "<hr>";
$cont = 0;
$foo = function($item,$key,&$aux){
$aux++;
};
array_walk($sampleArray,$foo,&$cont);
echo $cont; // it is 8, perfect but Deprecated: Call-time pass-by-reference
has been deprecated
Expected result:
----------------
0,8,8 should by right
but
0,0,8
